It is estimated that around 20% of the world's population smoke - one in five people. Someone, somewhere, dies of a tobacco-related illness every 8 seconds - whether that is lung cancer, asthma, emphysema or bronchitis. And it costs a fortune. Smoking is a choice - often one people make when they are teenagers, and keen to look cool. It is one that most of them will live to regret. This book offers a way out of that regret, to a smoke-free, healthier and better-off future.
